The Villainous Siblings want to Survive

Narumi and Natsuki Nakama died in an unfortunate accident on their way home after trying to save a kid from getting run over.

After waking up, they find themselves in the bodies of Adelaide and Alistar Viotto, the notorious villainous siblings in the novel.

Knowing death is only a few years away, they try their best to change their ways but...

"Rumors are he's gone crazy"

"He'll kill us all!"

"She's just a leach for the Duke"

"Even the crown prince threw her aside"

If they want a villain, then that's exactly what they're going to get. They'll play nice long enough for them to fall under their control.

But the question is...
Will they survive until the end?

Also, I changed the title name but didn't want to go through the work of changing the book cover because I'm LAaaaazy.
